There are many reasons for the thread breakage of the CS64 digital control garments making machine multineedle quilting machine. It is necessary to investigate one by one, find the reason, and then prescribe the right medicine to solve the problem. Today I will give you a summary of the reasons and solutions for the thread breakage of the CS64 digital control garments making machine multineedle quilting machine.

Broken thread head analysis: If the thread breaker is ponytail-shaped, it may be that the thread hook has burrs, the thread clamp is too tight, and the thread take-up spring is too large. If the broken thread ends in a cut shape, it may be that the position of the relevant mechanical structure of th  e CS64 digital control garments making machine multineedle quilting machine has c  hanged, the disassembly and assembly process did not follow the original position during the disassembly and assembly process, the parts are damaged by the collision of broken needles and other workpieces, and the edges of the parts have burrs, etc. .  If one or two strands of yarn break on a thread, it may be caused by the height of the presser foot.

There are burrs or rough surface from the thread ball to the needle threading link, and the upper thread is damaged and the hair is broken

Solution: All ring nodes of the upper thread are polished, and the corners should be smoothly processed.
